AAke Nordlund, Astronmical Observatory, Juliane Maries Vej 30, DK-2100 Copenhagen O, Denmark. aake@astro.ku.dkBrief Description of Application:
Number of Lines of Code: Around 10000
Target Platforms and HPF Compilers Used:
Coding Styles (data decompositions, computational methods):
Extrinsic Interfaces Used (and reasons):
Performance Information, if Available (including any possible comparisons to MPI and/or OpenMP):
Basic stencils run at around 80 Mflops/PE on T3E in non-distributed dimensions, and around 40 Mflops/PE for the distributed dimension. Performance grows linearly with number of PE's. Single processor performance is somewhat better on the IBM SP2. (See also http://www.tac.dk/~ossi/projects/cineca/tuneT3E.html)
Please comment on any aspects of the application that might be interesting, including any problems using HPF effectively:
